1比1的图表 [英] Chart with 1:1 scale
问题描述
我想使用两个轴的相同比例绘制一个图表（所以图形应该是一个正方形） 。在x和y两者的时刻，X轴是y轴长度的两倍。我知道可以移动图表的边界。但是，我希望我的图表是一个正方形，这是很难手动实现的。是否可以在Excel 2013上自动执行？如果是，怎么样？如果没有，你能否推荐一些可以帮助我的其他程序？
我希望我的问题有道理。
$ b $我非常感谢你的帮助！谢谢！
这是一个更通用的解决方案，解决了xy图表中两个轴的等比例缩放问题。 >
Excel通常自动缩放两个轴，并且不提供保持x和y等级相等的选项。
以下VBA-Module准确地将缩放设置为最适合 diagramArea （边界框）中图的 plotArea 。
它首先将 plotArea 最大化，然后看起来，哪个轴将以相等的比例缩小。

I have some problems plotting charts on Excel 2013.
I want to plot a graph using the same scale for both axes (so the graph should be a square). At the moment step for both x and y are the same but the x axis is about twice the length of y axis. I know it's possible to move the boundaries of the chart. However, I want my chart to be exactly a square, which is quite difficult to achieve manually. Is it possible to do that automatically on Excel 2013? If yes, how? If not, could you please recommend me some other programs which could help me out?
I hope my question makes sense.
I really appreciate your help! Thanks!
Here is a more general solution to the problem of equal scaling of both axes in xy-charts.
Excel usually autoscales the two axes and does not provide an option to keep x and y-scales equal.
The following VBA-Module accurately sets the scaling to best fit the plotArea of the diagram in the diagramArea (the bounding box).
It first blows up the plotArea to the maximum and then looks, which axis is to be reduced for equal scales.
Option Explicit

' Default borders between plot area and chart area

Const BORDER_LEFT = 4
Const BORDER_RIGHT = 4
Const BORDER_TOP = 29
Const BORDER_BOTTOM = 4
